Shell Wax is a wax glue that is used for snails. It only appears in the episode "Karate Island." It is used by SpongeBob to clean Gary's shell.


It is a small orange and yellow bottle. It has a Gary-looking snail on it. In dark green writing, it says Shell Wax in capital letters.


SpongeBob douses himself in the wax. He then rubs his back all over Gary's shell. When he finishes, his back is completely burned away.


  • Shell Wax may be a parody of Turtle Wax. However, Turtle Wax is used on cars, not turtles or snails.
